Itadaki Street DS (いただきストリートDS) is a game for the Nintendo DS. It was created by Square Enix. Like other installments in the Itadaki Street series, Itadaki Street DS is a Monopoly-like game that has some Mario Party-esque elements added to it due to the appearance of several Mario characters (minigames, for example). It was released on June 21st, 2007 only in Japan.

Players move around the board, buying shops and collecting money from others who land on their shop spaces. Depending on circumstances, some players can forcibly take over another player's shop spaces, or make them inactive for a turn. Players can also hold shares of a block of spaces so that they get paid when someone lands on any space in that block, even if it is not their own.

Players get bonuses for leveling up, which is done by passing four special spaces on the board (each marked with a suit- Club, Diamond, Heart, and Spade) and then going to the Bank space. If the player lands on one of these special spaces instead of passing them, they get a chance to randomly draw a "chance card", which affects gameplay or a player. Usually, the goal is to reach a certain total property value and get to the Bank, or to make a player bankrupt. There is also a special "Casino" space where themed games of chance occur.

Shop: The player can use his money to buy it. If this shop is owned by somebody else, the player must pay its price. If this shop is already owned by the one that lands on it, he can invest money in one of his shops.

Boon Square: The player gets a quarter of all the fees for one turn.

Boom Square: The player gets the half of all the fees for one turn.

Vacant Plot: The player can build anything on it.

Casino: The player can play a minigame and win some money, stocks or suits.

Break Square: All the player's shops get closed for a turn.

Suit Square: The player gets a suit and chooses a chance card if he lands on it.

Chance Square: The player chooses a chance card.

Cannon Square: The player goes to the chosen opponent's location.

Warp Square (Either a Warp Pipe or a Portal): The player warps to the Warp Square of the same color.

Switch Square: The Board's shape changes.

Magmalicious Square: If the Square is active, the player goes to an inactive Magmalicious Square and then it becomes inactive. It only appears in the Death Volcano.

Suit Change Square: The suit offered by the square is not fixed; it changes as players pass by it.

Die Square: The player rolls another die.

Bank Square: All players start and end in this square. When a player passes by this square, they may buy stocks. If the player bring the four suits to the Bank, they get a Salary and their level increases by one. When they have the goal assets, they have to go to the bank in order to win.

It has been requested that this article be rewritten because the section, especially on stocks, is unclear to users who have not played the game and possibly includes player strategies, which are not allowed in articles.

All shops are divided in many areas or blocks, each one which a name and a color. Most areas contain four shops. Shops start with a given price when players buy them, and they may invest on it later when they land on it to raise its price and value. If players get another shop in the same area as other owned shops, the shops' prices grow, and the player can invest more money on that shop. The player can achieve a monopoly by owning all shops in the area. Shops in monopolized areas accept even bigger invests that can be used increase stock price to benefit the player.

A player in the bank or a broker square may buy stocks. The player can choose any block; if the player has an area with shops to invest in, the player will mostly invest on that area to get money from the invests, and if the player owns no area but an opponent owns one, the player may buy stocks on that area to receive money when the opponent invests. Also, if the player has stocks in the same area a player in first place, the player may sell 10 stocks in each turn to lower the assets. This is an offensive technique performed by Rank S Characters. When a player buys more than 10 stocks, the stock prize rises an 8%, and when a player sells more than 10 stocks, the stock prize falls an 8%. Players may buy as a max amount 99 stocks per bank/broker pass (which is the recommended amount, and all Rank B, A and S players will buy MAX stocks and invest MAX capital in their shops) and can hold a max amount of 999 stocks in an area. Also, players may invest only the specific MAX amount in a shop when they land on it. If this amount is 1000G or more, the player may invest only 999G per land.

Players may also force buyout on the opponents' shops when they land on them. To buy a shop out, the player must pay 5x its real value. Buyouts are often made in late game to monopolize areas or to get rid of the opponents' monopolized areas by buying out the cheapest property. To prevent buyouts, players may invest on their small shops to make them more expensive. The shop design and material changes depending on the price.

Each AI will invest differently: Rank D AI limit themselves to buy 29 stocks per bank pass and 100G per invest, and they very rarely force a buyout. Rank C AI limit themselves to buy 49 stocks per bank pass and 200G per invest. Rank B AI invest the max amount of stocks per bank pass and invest the max amount of money in their shops, but they invest so early and even when they have a few amount of stocks that the raised price may end being too expensive for them, so they cannot get more stocks. Rank A also invest the max amount but they don't invest when they have few stocks, they wait until they get a good amount of stocks and then they invest and get a big amount of money. They also try to buy stocks on the opponents' areas to get extra money. Rank S also invest that way, but they sell stocks in purpose in opponents' areas to lower their assets. Rank B, A and S often buyout to get three shops or monopoly in an area or to prevent an opponent from investing in a monopolized area.

There are special spaces with a "Sale" sign on them. In those spaces, the player can build one of the following:

Gate: It starts with a price of 10G, and when somebody passes by it, that player has to pay the price of the Gate and it increases by 10G. Platypunk, Slime, Birdo, Donkey Kong, Dragonlord and Bowser often build it.

Circus Tent: The tent price starts being 100G, and if the owner lands on it he may increase it to 500G, 1000G, and finally, 2000G. The player has to pay 100G for each investment and the Circus Tent's value also increases by 100G. Luigi, Daisy, Toad and Yangus often build it.

Balloon Landing: The owner can fly anywhere when he lands on it. Other players have to pay 10% of the owner's salary. Mario, Bianca, Alena, Peach and Yoshi often build it.

Shrine: The owner can get a 5% bonus on all his assets if he lands on it. Other players have to pay 10% of all their assets, making it one of the most expensive buildings. But it can be easily bought out with 1000G, which is a small amount of money in the late stages of the game. Pudding, Kiryl, Jessica and Angelo often build it.

Bar: The owner can invite everybody to a party in the bar, which means that everybody must warp to the Bar space. If other players land on it, they must give the owner a "gift" of 30GxLVL. Wario, Waluigi and Hassan often build it.

Real Estate Agency: The owner can buy any ownerless shop. If other players land on it, they must "sleep" and their shops close for a turn. It is the least used building in all the game and the AI buys it very rarely.

Wood Shop: It acts like a normal shop. But since it is worth 1000G, when it is built, the stock price of the area where it was built rises highly. A good strategy with those buildings for the player is to get more than 99 Stocks in an area where they have any building and then turn it into a Wood Shop to raise their asset value. They must have at least 850G in money, because the strategy could fail if they are prompted to sell stocks and then they have to sell most of the area's stocks and then win very little money. B, A and S-Ranked characters may use this strategy.

All vacant plots are worth 200G, and the Wood Shop is worth 1000G. You can renovate a vacant plot whenever you want, and you get 150G for the destruction of the former building, which means that you only have to pay 50G for a normal building and 850G for a Wood Shop. You will get 750G for the destruction of a Wood Shop. As shown before, what the AI builds in a Vacant Plot depends in the character.

There are 22 playable characters in Itadaki Street DS: Eleven from the Mario series and eleven from the Dragon Quest series. Although only four of the characters from both series are playable to begin with, the others can be unlocked by playing through the Tour Mode of the game. Additionally, there are also three Support/Guest characters that players can summon with the help of a card, but are not playable. Players are also able to create and customize their own characters.

When a player lands on the Casino square (Which was renamed to Arcade square in Fortune Street), that player gets to play a game of chance. There are four of them:

Itadaki Slot: The Player rolls a slot to get some prizes. The player must make rows of pictures to win. Three Slimes/Goombas are worth 100GxLVL, two Slimes/Goombas are worth 30GxLVL, one Slime/Goomba is worth 10GxLVL, three Wild Cards are worth one Wild Card, three Warp Pipes/Chimera Wings let the player warp to any square and three Stocks (株) give the player five Stocks x LVL in the most valuable area.

Amida Pipe: This game takes place in the Warp Zone from Super Mario Bros.. The player must choose one of the three pipes and the pipe will either lead to coins (10GxLVL each one), a ? Block that may have coins, a mushroom that lets one of the player's shops grow, a Wild Card or a Poison Mushroom that makes the player sleep for one turn. One of the pipes leads to a Piranha Plant. If the player chooses that one, Mario loses a life and the player gets no reward.

Silver Tarot: The player is given some concealed Tarot cards, and they must choose two. The first card decides which players are gonna get something (The one in last place, everyone except the player, etc), and the second card decides the event. The events usually reward the player(s) with money or the effect of a boon square, except for the Grim Reaper card, that makes the player(s) sleep and plays the same fanfare that is heard when somebody gets chance card #13.

Monster Colosseum: A list of five Dragon Quest monsters appear, and the players must choose one of them. After the monsters are chosen, they will fight and the owner of the last monster alive wins some Gold.
